- 6Mm Hardened Steel Chain — Serious Cut Protection — Each link is 6mm thick hardened steel, wrapped in a protective fabric sleeve. Resists bolt cutters, hacksaws, and pry attacks far better than standard cable locks. The 1-metre (39in) length wraps through frame, wheels, and any fixed object with room to spare. If you leave your bike for more than a few minutes, this is the level of protection you need.

Set your own code in seconds, reset whenever you like. No keys to lose, no spares to cut, no locksmith needed. Your code, your control.
- Built For Australian Outdoor Conditions — Fabric chain cover prevents rattling and protects your frame from scratches. Inner chain links are corrosion-treated to withstand coastal salt air, summer heat, and winter rain. UV-resistant lock body won't crack or fade in the Australian sun. Leave it outside — it's built for it.
- Locks Bikes, Scooters, Motorcycles & More — Thread the chain through wheels, frames, gates, fences, or multiple bikes on one rack. Works for electric scooters, motorbikes, mopeds, strollers, toolboxes, sheds, and ladders. The 6mm chain cannot be defeated by the casual wire cutters that beat cable locks.
- 30-Second Setup — Carry Anywhere — Default code 0000. Push the reset button, roll to your new 5-digit code, release. Done. Compact coil design stows in a pannier, backpack, or basket. Lightweight enough for daily carry but heavy enough that thieves know you mean business.

Frequently Asked Questions
Fitment, maintenance and shipping — the questions we answer most often for this product.
What is the WOWSPORT Bike Chain Lock 5-Digit Combination — 1m Long 6mm Thick Heavy Duty Anti-Theft Steel Chain Lock for Bicycle, E-Bike, Scooter & Motorcycle, Keyless Resettable Outdoor Security Lock, Black designed for?
6Mm Hardened Steel Chain — Serious Cut Protection — Each Link Is 6Mm Thick Hardened Steel, Wrapped In A Protective Fabric Sleeve. Resists Bolt Cutters, Hacksaws, And Pry Attacks Far Better Than Standard Cable Locks. The 1-Metre (39In) Length Wraps Through Frame, Wheels, And Any Fixed Object With Room To Spare. If You Leave Your Bike For More Than A Few Minutes, This Is The Level Of Protection You Need.
Which bike lock is hardest to cut?
A U-lock with a 19mm hardened steel shackle. Both ends lock into the body, so an angle grinder or bolt cutter has to defeat two points instead of one, and the shackle cannot be twisted against the ground the way a chain can.
How long should a bike lock be?
65cm suits a frame plus a fixed rack. 100 to 103cm is the all-rounder: frame, one wheel and a post with a little slack. 120cm is for two bikes, or a thick post plus both wheels. Length costs weight and money, so buy for where you actually park.
Can a cable lock be cut?
Yes. A braided steel cable stops someone walking off with an unlocked bike, not someone with cable cutters and thirty seconds. Treat a cable as a second lock that secures the wheels, and use a U-lock or chain as the primary lock on the frame.
What if I forget my combination?
There is no master key and no recovery code, by design — a master key would open every lock we sell. A locksmith can cut the cable or chain, but the lock will not survive it. Set the code somewhere you will find it that is not your phone.
Will a U-lock scratch my frame?
Our U-lock ships with a full silicone sleeve over the shackle, and the cable is PVC coated, so the parts that touch the frame are soft. The bracket mounts to the frame with rubber shims. Any lock will mark paint if it is rattled around loose, which is why the bracket matters more than the coating.
